The above-mentioned general or preferred radical definitions apply both to the end products of the formula (I) and also, correspondingly, to the starting materials or intermediates required in each case for the preparation. These radical definitions can be combined with each other as desired, i.e. including combinations between the given ranges.

Using, for example, 5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimidine-2-sulphonyl chloride and 2-amino-phenol as starting materials, the course of the reaction in the process according to the invention can be illustrated by the following equation:

In the formula (II), Q¹, Q², R¹ and R² each preferably have those meanings which have already been indicated above, in connection with the description of the compounds of the formula (I) according to the invention, as being preferred for Q¹, Q², R¹ and R².

The starting materials of the formula (II) are known and/or can be prepared by processes known per se (cf. EP 142152, EP 244847, EP 375076, U.S. Pat. No. 4,605,433, U.S. Pat. No. 5,163,995, WO 89/10368).

In the formula (III), Ar preferably has that meaning which has already been indicated above, in connection with the description of the compounds of the formula (I) according to the invention, as being preferred for Ar.

The starting materials of the formula (III) are known and/or can be prepared by processes known per se (cf. EP 142152, EP 244847, EP 375076, U.S. Pat. No. 4,605,433, U.S. Pat. No. 5,163,995, WO 89/10368).

Suitable reaction auxiliaries for the process according to the invention are generally the customary inorganic or organic bases or acid acceptors. These preferably include alkali metal or alkaline earth metal acetates, amides, carbonates, bicarbonates, hydrides, hydroxides or alkoxides, such as, for example, sodium acetate, potassium acetate or calcium acetate, lithium amide, sodium amide, potassium amide or calcium amide, sodium carbonate, potassium carbonate or calcium carbonate, sodium bicarbonate, potassium bicarbonate or calcium bicarbonate, lithium hydride, sodium hydride, potassium hydride or calcium hydride, lithium hydroxide, sodium hydroxide, potassium hydroxide or calcium hydroxide, sodium methoxide or potassium methoxide, sodium ethoxide or potassium ethoxide, sodium n- or i-propoxide or potassium n- or i-propoxide, sodium n-, i-, s- or t-butoxide or potassium n-, i-, s- or t-butoxide; furthermore also basic organic nitrogen compounds, such as, for example, trimethylamine, triethylamine, tripropylamine, tributylamine, ethyldiisopropylamine, N,N-dimethyl-cyclohexylamine, dicyclohexylamine, ethyl-dicyclohexylamine, N,N-dimethyl-aniline, N,N-dimethyl-benzylamine, pyridine, 2-methyl-, 3-methyl-, 4methyl-, 2,4-dimethyl-, 2,6-dimethyl-, 3,4-dimethyl- and 3,5-dimethyl-pyridine, 5-ethyl-2-methyl-pyridine, 4-dimethylamino-pyridine, N-methylpiperidine, 1,4-diazobicyclo[2.2.2]-octane (DABCO), 1,5-diazabicyclo[4.3.0]-non-5-ene (DBN), or 1,8-diazabicyclo[5.4.0]-undec-7-ene (DBU).

Suitable diluents for carrying out the process according to the invention are in particular inert organic solvents. These preferably include aliphatic, alicyclic or aromatic, optionally halogenated hydrocarbons, such as, for example, benzine, benzene, toluene, xylene, chlorobenzene, dichlorobenzene, petroleum ether, hexane, cyclohexane, dichloromethane, chloroform, carbon tetrachloride; ethers, such as diethyl ether, diisopropyl ether, dioxane, tetrahydrofuran or ethylene glycol dimethyl ether or ethylene glycol diethyl ether; ketones, such as acetone, butanone or methyl isobutyl ketone; nitriles, such as acetonitrile, propionitrile or butyronitrile; amides, such as N,N-dimethylformamide, N,N-dimethylacetamide, N-methyl-formanilide, N-methyl-pyrrolidone or hexamethylphosphoric triamide; esters such as methyl acetate or ethyl acetate; sulphoxides, such as dimethyl sulphoxide; alcohols, such as methanol, ethanol, n- or i-propanol, ethylene glycol monomethyl ether, ethylene glycol monoethyl-ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, mixtures thereof with water or pure water.

When carrying out the process according to the invention, the reaction temperatures can be varied within a relatively wide range. In general, the reaction is carried out at temperatures between 0° C. and 100° C., preferably between 10° C. and 60° C.

The process according to the invention is generally carried out under atmospheric pressure. However, it is also possible to carry out the process according to the invention under elevated or reduced pressure—in general between 0.1 bar and 10 bar.

For carrying out the process according to the invention, the starting materials are generally employed in approximately equimolar amounts. However, it is also possible to employ one of the components in a relatively large excess. The reaction is generally carried out in a suitable diluent in the presence of a reaction auxiliary, and the reaction mixture is generally stirred at the required temperature for several hours. Work-up is carried out by customary methods (cf. the Preparation Examples).

The active compounds of the formula (I) according to the invention can be used as defoliants, desiccants, haulm killers and, especially, as weed-killers. By weeds, in the broadest sense, there are to be understood all plants which grow in locations where they are not wanted. Whether the substances according to the invention act as total or selective herbicides depends essentially on the amount used.

The active compounds according to the invention can be used, for example, in connection with the following plants:

Dicotyledonous weeds of the genera: Sinapis, Lepidium, Galium, Stellaria, Matricaria, Anthemis, Galinsoga, Chenopodium, Urtica, Senecio, Amaranthus, Portulaca, Xanthium, Convolvulus, Ipomoea, Polygonum, Sesbania, Ambrosia, Cirsium, Carduus, Sonchus, Solanum, Rorippa, Rotala, Lindernia, Lamium, Veronica, Abutilon, Emex, Datura, Viola, Galeopsis, Papaver, Centaurea, Trifolium, Ranunculus and Taraxacum.

Dicotyledonous crops of the genera: Gossypium, Glycine, Beta, Daucus, Phaseolus, Pisum, Solanum, Linum, Ipomoea, Vicia, Nicotiana, Lycopersicon, Arachis, Brassica, Lactuca, Cucumis and Cucurbita.

Monocotyledonous weeds of the genera: Echinochloa, Setaria, Panicum, Digitaria, Phleum, Poa, Festuca, Eleusine, Brachiaria, Lolium, Bromus, Avena, Cyperus, Sorghum, Agropyron, Cynodon, Monochoria, Fimbristylis, Sagittaria, Eleocharis, Scirpus, Paspalum, Ischaemum, Sphenoclea, Dactyloctenium, Agrostis, Alopecurus and Apera.

Monocotyledonous crops of the genera: Oryza, Zea, Triticum, Hordeum, Avena, Secale, Sorghum, Panicum, Saccharum, Ananas, Asparagus and Allium.

However, the use of the active compounds according to the invention is in no way restricted to these genera, but also extends in the same manner to other plants.

The compounds are suitable, depending on the concentration, for the total control of weeds, for example on industrial terrain and rail tracks, and on paths and squares with or without tree plantings. Equally, the compounds can be employed for controlling weeds in perennial crops, for example afforestations, decorative tree plantings, orchards, vineyards, citrus groves, nut orchards, banana plantations, coffee plantations, tea plantations, rubber plantations, oil palm plantations, cocoa plantations, soft fruit plantings and hopfields, in lawns, turf and pasture-land and for the selective control of weeds in annual crops.

The compounds of the formula (I) according to the invention are particularly suitable for the selective control of monocotyledonous and dicotyledonous weeds in monocotyledonous and dicotyledonous crops, both pre-emergence and post-emergence.

The active compounds of the formula (I) according to the invention to a certain extent also have strong microbicidal action and can be practically employed for controlling undesirable microorganisms. The active compounds are consequently also suitable for use as fungicides and bactericides.

Fungicides in plant protection are employed for controlling Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes and Deuteromycetes.

Bactericides in plant protection are employed for controlling Pseudomonadaceae, Rhizobiaceae, Enterobacteriaceae, Corynebacteriaceae and Streptomycetaceae.

Some causative organisms of fungal and bacterial diseases which come under the generic names listed above may be mentioned as examples, but not by way of limitation:

Xanthomonas species, such as Xanthomonas campestris pv. oryzae; Pseudomonas species, such as Pseudomonas syringae pv. lachrymans; Erwinia species, such as Erwinia amylovora; Pythium species, such as Pythium ultimum; Phytophthora species, such as Phytophthora infestans; Pseudoperonospora species, such as Pseudoperonospora humuli or Pseudoperonospora cubensis; Plasmopara species, such as Plasmopara viticola; Bremia species, such as Bremia lactucae; Peronospora species, such as Peronospora pisi or P. brassicae; Erysiphe species, such as Erysiphe graminis; Sphaerotheca species, such as Sphaerotheca fuliginea; Podosphaera species, such as Podosphaera leucotricha; Venturia species, such as Venturia inaequalis; Pyrenophora species, such as Pyrenophora teres or P. graminea (conidia form: Drechslera, syn: Helminthosporium); Cochliobolus species, such as Cochliobolus sativus (conidia form: Drechslera, syn: Helminthosporium); Uromyces species, such as Uromyces appendiculatus; Puccinia species, such as Puccinia recondita; Scierotinia species, such as Sclerotinia sclerotiorum; Tilletia species, such as Tilletia caries; Ustilago species, such as Ustilago nuda or Ustilago avenae; Pellicularia species, such as Pellicularia sasakii;

The good toleration, by plants, of some of the active compounds, at the concentrations required for controlling plant diseases, permits treatment of aerial parts of plants, of vegetative propagation stock and seeds, and of the soil.

The active compounds according to the invention can be employed here very successfully for controlling diseases in fruit and vegetable growing, such as, for example, against Podosphaera and Sphaerotheca species, and also for controlling rice diseases, such as, for example, Pyricularia oryzae.

The active compounds can be converted into the customary formulations, such as solutions, emulsions, wettable powders, suspensions, powders, dusting agents, pastes, soluble powders, granules, suspo-emulsion concentrates, natural and synthetic materials impregnated with active compound, and very fine capsules in polymeric substances.

These formulations are produced in a known manner, for example by mixing the active compounds with extenders, that is liquid solvents and/or solid carriers, optionally with the use of surfactants, that is emulsifiers and/or dispersing agents and/or foam-forming agents.

If the extender used is water, it is also possible to employ, for example, organic solvents as auxiliary solvents. Suitable liquid solvents are essentially: aromatics, such as xylene, toluene or alkylnaphthalenes, chlorinated aromatics and chlorinated aliphatic hydrocarbons, such as chlorobenzenes, chloroethylenes or methylene chloride, aliphatic hydrocarbons, such as cyclohexane or paraffins, for example petroleum fractions, mineral and vegetable oils, alcohols, such as butanol or glycol as well as their ethers and esters, ketones, such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, strongly polar solvents, such as dimethylformamide and dimethyl sulphoxide, and also water.

Suitable solid carriers are: for example ammonium salts and ground natural minerals, such as kaolins, clays, talc, chalk, quartz, attapulgite, montmorillonite or diatomaceous earth, and ground synthetic minerals, such as highly disperse silica, alumina and silicates, as solid carriers for granules there are suitable: for example crushed and fractionated natural rocks such as calcite, marble, pumice, sepiolite and dolomite, as well as synthetic granules of inorganic and organic meals, and granules of organic material such as sawdust, coconut shells, maize cobs and tobacco stalks; as emulsifying and/or foam-forming agents there are suitable: for example nonionic and anionic emulsifiers, such as polyoxyethylene fatty acid esters, polyoxyethylene fatty alcohol ethers, for example alkylaryl polyglycol ethers, alkylsulphonates, alkyl sulphates, arylsulphonates as well as protein hydrolysates; as dispersing agents there are suitable: for example lignin-sulphite waste liquors and methylcellulose.

Tackifiers such as carboxymethylcellulose and natural and synthetic polymers in the form of powders, granules or latices, such as gum arabic, polyvinyl alcohol and polyvinyl acetate, as well as natural phospholipids, such as cephalins and lecithins, and synthetic phospholipids, can be used in the formulations. Further additives can be mineral and vegetable oils.

It is possible to use colorants such as inorganic pigments, for example iron oxide, titanium oxide and Prussian Blue, and organic dyestuffs, such as alizarin dyestuffs, azo dyestuffs and metal phthalocyanine dyestuffs, and trace nutrients such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

The formulations in general contain between 0.1 and 95 per cent by weight of active compound, preferably between 0.5 and 90%.

The active compounds according to the invention can be used as such or, in their formulations, also as a mixture with known herbicides for the control of weeds, in which case ready-to-use formulations or tank mixes are possible.

Suitable co-components for the mixtures are known herbicides, for example anilides such as, for example, diflufenican and propanil; arylcarboxylic acids such as, for example, dichloropicolinic acid, dicamba and picloram; aryloxyalkanoic acids such as, for example, 2,4-D, 2,4-DB, 2,4-DP, fluroxypyr, MCPA, MCPP and triclopyr; aryloxy-phenoxy-alkanoic esters such as, for example, diclofop-methyl, fenoxaprop-ethyl, fluazifop-butyl, haloxyfop-methyl and quizalofop-ethyl; azinones such as, for example, chloridazon and norflurazon; carbamates such as, for example, chlorpropham, desmedipham, phenmedipham and propham; chloroacetanilides such as, for example, alachlor, acetochlor, butachlor, metazachlor, metolachlor, pretilachlor and propachlor; dinitroanilines such as, for example, oryzalin, pendimethalin and trifluralin; diphenyl ethers such as, for example, acifluorfen, bifenox, fluoroglycofen, fomesafen, halosafen, lactofen and oxyfluorfen; ureas such as, for example, chlortoluron, diuron, fluometuron, isoproturon, linuron and methabenzthiazuron; hydroxylamines such as, for example, alloxydim, clethodim, cycloxydim, sethoxydim and tralkoxydim; imidazolinones such as, for example, imazethapyr, imazamethabenz, imazapyr and imazaquin; nitriles such as, for example, bromoxynil, dichlobenil and ioxynil; oxyacetamides such as, for example, mefenacet; sulphonylureas such as, for example, amidosulfuron, bensulfuron-methyl, chlorimuron-ethyl, chlorsulfuron, cinosulfuron, metsulfuron-methyl, nicosulfuron, primisulfuron, pyrazosulfuron-ethyl, thifensulfuron-methyl, triasulfuron and tribenuron-methyl; thiolcarbamates such as, for example, butylates, cycloates, di-allates, EPTC, esprocarb, molinates, prosulfocarb, thiobencarb and triallates; triazines such as, for example, atrazine, cyanazine, simazine, simetryne, terbutryne and terbutylazine; triazinones such as, for example, hexazinone, metamitron and metribuzin; others such as, for example, aminotriazole, benfuresate, bentazone, cinmethylin, clomazone, clopyralid, difenzoquat, dithiopyr, ethofumesate, fluorochloridone, glufosinate, glyphosate, isoxaben, pyridate, quinchlorac, quinmerac, sulphosate and tridiphane.

A mixture with other known active compounds, such as fungicides, insecticides, acaricides, nematicides, bird repellants, plant nutrients and agents which improve soil structure, is also possible.

The active compounds can be used as such, in the form of their formulations or in the use forms prepared therefrom by further dilution, such as ready-to-use solutions, suspensions, emulsions, powders, pastes and granules. They are used in the customary manner, for example by watering, spraying, atomizing or scattering.

The active compounds according to the invention can be applied either before or after emergence of the plants. They can also be incorporated into the soil before sowing.

The amount of active compound used can vary within a substantial range. It depends essentially on the nature of the desired effect. In general, the application rates are between 1 g and 10 kg of active compound per hectare of soil surface, preferably between 5 g and 5 kg per ha.

The preparation and the use of the active compounds according to the invention can be seen from the examples below.

PREPARATION EXAMPLES Example 1

At room temperature (approximately 20° C.), a mixture of 2.1 g (10 mmol) of 2-methylthio-6-n-butyroyl-aniline, 2.5 g (10 mmol) of 5,7-dimethyl-1,2,4-triazolo[1,5-a]pyrimdine-2-sulphonyl chloride and 30 ml of pyridine is stirred for approximately 15 hours. The pyridine is subsequently carefully distilled off under water pump vacuum and the residue is taken up with 100 ml of methylene chloride and washed twice each with 2N hydrochloric acid and with water, dried with magnesium sulphate and filtered. The filtrate is concentrated under water pump vacuum, the amorphous residue is crystallized by treatment with ethanol and the product is isolated by filtration with suction.

This gives 2.8 g (67% of theory) of 5,7-dimethyl-N-(2-methylthio-6-n-butyroyl-phenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulphonamide of melting point 138° C.

Example 2

3.2 g (7.5 mmol) of 5,7-dimethyl-N-(2-methylthio-6-n-butyroyl-phenyl)- 1,2,4-triazolo[1,5-a]pyrimidine-2-sulphonamide are initially charged in 60 ml of chloroform, and the solution is admixed with 1.8 g of 3-chloro-perbenzoic acid (70% strength). The reaction mixture is then stirred at room temperature (approximately 20° C.) for approximately 60 minutes and subsequently concentrated under water pump vacuum. The residue is digested with 40 ml of ethanol and the resulting crystalline product is isolated by filtration with suction.

This gives 2,3 g (70% of theory) of 5,7-dimethyl-N-(2-methylsulphinyl-6-n-butyroyl-phenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulphonamide of melting point 255° C. (with decomposition).

Example 3

2.1 g (5 mmol) of 5,7-dimethyl-N-(2-methylthio-6-n-butyroyl-phenyl)- 1,2,4-triazolo[1,5-a]pyrimidine-2-sulphonamide are initially charged in 50 ml of chloroform, and the solution is admixed with 2.8 g of 3-chloro-perbenzoic acid (70% strength). The reaction mixture is then stirred at room temperature (approximately 20° C.) for approximately 2 hours and subsequently concentrated under water pump vacuum. The residue is digested with 30 ml of ethanol and the resulting crystalline product is isolated by filtration with suction.

This gives 2.0 g (89% of theory) of 5,7-dimethyl-N-(2-methylsulphonyl-6-n-butyroyl-phenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulphonamide of melting point 236° C. (with decomposition).
